ImportError: No module named 'jupyter_client'

Question

我正在尝试在我的 debian jessie 机器上安装 RODEO。我已经成功地 pip 安装了 rodeo 并且安装完成没有任何问题。但是，当我在命令行中键入 rodeo 时，我收到以下错误消息：

xxxxxx@yyyyy:~$ rodeo 
/usr/local/lib/python3.4/dist-packages/IPython/kernel/__init__.py:13: ShimWarning: The `IPython.kernel` package has been deprecated. You should import from ipykernel or jupyter_client instead.
  "You should import from ipykernel or jupyter_client instead.", ShimWarning)

  File "/usr/local/lib/python3.4/dist-packages/rodeo/kernel.py", line 3, in <module>
    from jupyter_client import BlockingKernelClient
ImportError: No module named 'jupyter_client'

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "/usr/local/bin/rodeo", line 9, in <module>
    load_entry_point('rodeo==0.4.4', 'console_scripts', 'rodeo')()

    from ipykernel import comm, inprocess
ImportError: No module named 'ipykernel'

我已经安装了 ipython，有人可以解释一下吗？在 apt repos 中搜索 jupyter 客户端时，我找不到一个。任何帮助将不胜感激。

IPython 4.0 已 split 到许多包中，许多与笔记本和执行相关的包现在已成为 Jupyter 的一部分。

如果 rodeo 支持 4.0 API，您可以通过以下方式安装：

pip install --upgrade jupyter

(几乎任何与IPython3一起工作的东西都应该与IPython4和Jupyter一起工作，只要安装了额外的包。IPython 包括已移动导入的垫片。）

如果这不起作用，牛仔竞技现在可能需要 IPython 3.x。您可以通过以下方式将 IPython 固定到 3.x：

pip install 'ipython[notebook]<4'

ImportError: No module named 'jupyter_client'

ImportError: No module named 'jupyter_client'

python

ipython

python-3.x
